Strongly suggest two things:My M1A trigger seems to have a little hitch in it (you can hear a little click when you take up the first stage) - and the second stage is too light. It will almost pick up 3.5 pounds. Suggestions??? I already changed the spring a couple times. ???? Thanks in advance any any ideas or where to send it to get it tuned to NM specs.

I don't want to sound like I'm nitpicking, but you use Garnet Paper (which is cloth/drill backed abrasive paper for metal) and not sandpaper to add a little trigger pull weight. Sandpaper for wood will normally just tear and do no good. Normally one should use 320 gr. Garnet Paper for this job and at the VERY coarsest when a lot of weight has to be added, then one uses 220 Gr. Actually and for most people, it is better to use 320 grit and just have to run it through more times so you don't get too much trigger pull weight added on too quickly.If this is the case, you normally put a piece of sandpaper between the trigger and the disconnector, with the rough side facing the trigger, and pull it through several times. This takes just a little material off the back of the trigger, allowing the discon to rock slightly further forward. This should both eliminate the click, and increase the pull weight.
That said, before you actually do anything, let's see what Gus has to say about this idea.
That mostly depends on how long the hammer spring is. I always want a full length hammer spring around 2 1/8" or slightly more so there is more pull weight on the first stage and the second stage "feels" lighter because of it.Greetings,
In a properly functioning M14 FCG, how is that total pull weight typically divided up between the two stages? Thanks!
